摘要
介绍了采用专门研制的低频宽带振动测试系统，进行上海金茂大厦结构脉动反应测试的工作以及模态分析过程，将高层建筑安全性检测理论应用于实际典型工程。
By use of the especially developed low frequency wide range vibraion measremnt system, the acceleration history response of the Shanghai Jinmao Mansion was measured under environment excitation. The measuarent pmeess and the analysis work of the data are pmted in this paper.The frequencies, dynthec modes and damping coefficients have been identified. The saisfactory comparison betwee the identified results and the computed results demonstiae tha the smiced wh employed for the design of the Jinmao Mansion is reliabe .
